PCjs now saves your machine state using browser local storage, so any changes will be preserved when your browser closes, including diskette changes. To restore a diskette's original contents, press "Load Drive" again.
PCjs is highly configurable. Each configuration is a separate XML file that specifies the CPU, RAM, ROMs, diskette drives, hard drives, video adapter, serial ports, etc. Configurations also specify which disk images to automatically load. An entire machine state can be pre-loaded as well.
Below are some examples from our growing list of PCjs configurations, including Windows 1.01 running on an IBM PC XT.
The simulations do not send any information back to the server, unless a problem is detected and you explicitly agree to send your simulation state, to help the author diagnose the problem.
PCjs v1.08 adds soft-keyboard support, which isn't quite finished (sticky-shift and auto-repeat will be added in a future version), but it's good enough for use on iPads. See the list of PCjs configurations for those that include a soft keyboard. In addition, 1.08 adds support for server-side machine state storage, which allows you to save your machine states remotely and access them from any computer using the same server key. However, server-side storage is still a "work-in-progress," so for now, server keys will be distributed on an extremely limited basis.
PCjs v1.06c adds support for user-defined diskette images. Select "User-defined URL..." from the diskette list and click "Load Drive". Please see Creating PCjs-Compatible Disk Images in the documentation for more information about supported disk images.
PCjs v1.05b adds support for webkitAudioContext, bringing your simulated IBM PC's speaker to life. Relive the thrill of running MUSIC.BAS and listening to those classic tunes.
